In Defence of Euxenippus (32)

The most outrageous feature of your speech was the fact that often during the argument you let fall the remark—you thought that your motive in doing so passed unnoticed, though it was obvious—that Euxenippus was rich, and again, a little later, that he had amassed great wealth dishonestly. It has surely nothing to do with this case whether he is a man of large means or small, and to raise the matter is malicious and implies an unfair assumption regarding the jury, namely that they would base their verdict on other considerations than the point at issue and the question whether the man on trial is offending against you or not.
